An auxiliary heating system includes a furnace positioned within a building. The furnace includes an outlet duct and a thermostat electrically coupled to the furnace. The thermostat establishes a trigger temperature. A housing is provided to contain a combustible material. A discharge is coupled to the housing and discharges smoke produced from combustion of the combustible material. A conduit is coupled between the housing and the outlet duct to direct heat into the outlet duct. A damper is positioned within the conduit to restrict a flow of the heat into the outlet duct. A control circuit is coupled to the housing and electrically coupled to the thermostat and a power source. A fan is positioned within the conduit and electrically coupled to the control circuit. The fan is actuated when a temperature in the building falls below the trigger temperature to urge the heat into the outlet duct.
